Step 1. Convert 3 1/4 to an improper fraction.
3 * 4 + 1/4 - 1 5/8
Step 2. Simplify 3 * 4 to 12
12 + 1/4 - 1 5/8
Step 3. Simplify 12 + 1 to 13
13/4 - 1 5/8
Step 4. Convert 1 5/8 to an improper fraction.
13/4 - 1 * 8 + 5/8
Step 5. Simplify 1 * 8 to 8
13/4 - 8 + 5/8
Step 6. Simplify 8 + 5 to 13
13/4 - 13/8
Step 7. Find the Least Common Denominator (LCD) of 13/4, 13/8
LCD = 8
Step 8. Make the denominators the same as the LCD
13 * 2/ 4 * 2 - 13/8
Step 9. Simplify. Denominators are now the same
26/8 - 13/8
Step 10. Join the denominators
26 - 13/8
Step 11. Simplify
13/8
Step 12. Convert to a mixed fraction
1 5/8
Answer:
C 109
Step-by-step explanation:
First add all the known angles inside the triangle first to get 109°
Then since all angles in a triangle add to 180°
you take away 109 from 180 so
180-109 which equals 71
Then since all angles on a straight line add up to 180°
you take 71 from 180 so
180-71 = 109
so x = 109°
Answer: yes, 4/3 can be simplified
Step-by-step explanation:
Since it is an improper fraction, it can be simplified.
three goes into four once, And there is a remainder of one. so the new fraction is: 1 1/3
Answer:
25
Step-by-step explanation:
b the shapes are rectangele and triangele
c triangle base times hieght divided by 2 rectangele leingth times width
d rectangle- 3*5= 15
triangle 4*5=20 20/2=10
10+15=25
Answer:
x = 12
Step-by-step explanation:
5x - 17 = 43
5x = 43 + 17
5x = 60
x = 60 : 5
x = 12
